I agree.

At the very most, if you are really concerned about lack of agreement, having the feature in Linux generally may be a valid first step.  But only Linux and then just on ONE target platform doesnât make any sense.  There is nothing here that is target specific as far as I can tell, so a limitation to x86 is something I do not understand at all.
